Right now I'm done with almost 20GB download from the BSD machine to my laptop by ftp, and 5GB to the BSD from http, in the mean while I've done almost 40GB of torrentflux's checking existing data and I do a make install to a port, all in the same time and everything is working great. I hope it will continue to work just like this.
The hdd temperatures are:
# smartctl -A /dev/ad0 | grep Temp && smartctl -A /dev/ad4 | grep Temp
194 Temperature_Celsius 0x0022 095 081 000 Old_age Always - 48
194 Temperature_Celsius 0x0022 107 102 000 Old_age Always - 43
Roland, I have no connected any display to that machine.

Tools like mbmon can show you the different voltages that the power supply
produces. But current isn't measured in the different circuits, AFAIK. If you
see a drop in voltage before a reboot that would be a clear sign of
trouble. Unfortunately the chips that do the monitoring sometimes only provide
new values once every second. That is probably not fast enough to detect a
swift voltage drop.
There are devices (e.g. kill-a-watt) available that you can plug between the
power outlet and the PC that show you the total power consumption. See
The abovementioned link shows a decent system using between 118 and 205
Watt. So I'd be surprised if your 450 Watt powersupply wasn't sufficient.
(unless you have one of those graphics cards that is covered in fans and
heatsinks and that you could still use to fry an egg on.)
But I agree that it looks like a hardware problem. Unfortunately there are
multiple possible causes. Check to see if all the cabling and cards are
securely connected. Monitor the temperatures that the on-board sensors
report. Remove dust from heatsinks and fans. Check the electrolytic capacitors
on the motherboard. If the metal "lid" is bulging, it's busted.
